Williams-Sonoma has been selling fine cookware for more than 50 years. At this Williams-Sonoma store on the Promenade, customers can not only buy their cookware (or set up a gift registry), but attend how-t0 demonstrations, too. On Sundays, the store hosts cooking-technique classes, while on Tuesday, Thursday, Friday and Saturday, there are 11am sessions on topics like seasoning, creative cupcakes and even knife wielding for chefs.
